J'ReCLOSURE DEVICE.

Application filed April 3,

To @ZZ whom t may concern: n

Be it known that l, HARRY RUiNson, a citizen of the United` States, randa resident of Des Moines, in the county of Polk and State of Iowa, haveinvented a certain new and useful Jar-Closure Device, of which thefollowing is a specification.

The object of my invention is to provide a jar closure device of simple,durable and comparatively inexpensive construction.

More particularly, it is my intention to provide a closui'e member forjars o r the like, the closure member being so designed that it niay bereceived and coact with a portion of the jar for securely holding thecover member in position.

Still another object is to provide a cover member for a. jar, having apair of outwardly extending arms formed thereon and notches provided inthe jar for receiving the arms for securely holding the cover member inposition.

Still another object is to provide a cam surface adjacent to t-henotches in the jar, whereby a slight rotation of the cover member ineither direction will cause the-arms of the cover member to engage thecam surfaces for forcing the cover member downwardly against the jar,whereby it may be securely locked in position.

Still another object is to provide the arm :members on the cover longenough, so as to project out beyond the side of the jar, so as to formmeans, whereby it may be engaged for rotating the cover and moving it toeither open or closed position.

Still another object is to provide resilient bands formed on the arms ofthe cover member, so that the cover member may be yieldingly forcedint-o closed position.

With these and other objects in view, my invention consists in theconstruction, arrangement and combination of the various parts of mydevice, whereby the objects contemplated ai'e attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which:

Figure 1 is a side elevation of a jar with my improved cover membershown thereon.

line 3-3 of Figure 2, with the cover member shown in section.

Figure 4 is a top view of the cover inember; and

Figure 5 is a slight-ly modified form of the cover member.

In the accompanying drawings, l have used the reference numeral 10 toindicate an ordinary jar, which is provided with a conti'acted neck 11and an enlarged bead or rim 12 projecting upwardly vfrom the neck 11.

The rim 12 is provided with an enlarged opening 13 and a smallcontracted opening 14, whereby a shoulder or annular rabbet 15 isprovided. lThe passageway 16, which entends through the neck 11 issmaller in diameter than the opening` 14. The main body portion of thejar 10 is larger in diameter than the opening 16 in the neck 11. Thepurpose of the annular rabbet or shoulder 15 will be hereafter morefullv set forth. i'

The rim 12 is provided with a pair of openings 17, which aresubstantially the shape of aniiiverted T. The openings 17 are providedwith a pair of cani surfaces 18, as clearly illustrated in Figure 1ofthe drawings. At the eXtreme ends of the openings 17 and adj aeent tothe inner lower ends of the cam surfaces 18 are provided notches 19, thepurpose of which will be hereafter more fully set forth.

ln order to seal the jar,lprovide a cover member 20, having a shoulder21, which is designed to be received in the rabbet 15. A rubber band orjar ring 22may be used by placing it within the annular rabbet 15,whereby the cover member 20 will i'est thereon. The cover member 2O isprovided with a. pair of outwardly, oppositely extending arms 23. Thearms 23 are provided with a i'ubber ring 24. The upper portion of theopening 17 is just large enough to pei'iiiit the arms 23 to be extendedtherethrough.

When the arms 23 are extended therethrough, a portion thereof willprojectl out beyond the sides of the jar, so that they may be engaged bythe fingers of an operator for rotating the cover member inv eitherdirection a slight amount. The rubber band 24 will engage one of the camsurfaces 18 l member 25.

. 2U will cause the arms 23 tobe received in one oft the notches 19 ofeach oit the openings i7. 'li/V hen the arms 23 are received in thenotches 19 of the openings 17, then the jar cover member 2O will be heldin locked position.

When it is desired to open the jar, all that is necessary is to rot-atethe cover" member towards the upper extension ot the opening`17, andwhen the arms 23 register with the upper extension ot theopening 17,then the entire cover member may be lifted up and away from the jar. f

It will be understood that when it is desired to sealithe `jar, thecover member 20 may be rotated in either direction, and when doing so,the cover men'iher will be caused to `engage one of the notches 19 oithe openvThe jar l0 may be made of heavy glass or of some other suitablematerial. The cover member 20 may be-m'ade ott steel stampings or othersuitable material.

The'providingl of the rubber ringl 2d gives the cover member 20 a chanceto move up and-down a slight amount.

rEhe rubbenjarring 22 eausesthe connection or the sealing abilityotthecover meniber 20 tobe zgreatly increasedl .so that when the cover'member 20 in locked position, the contents of the j ar will bethoroughly sealed.v v

The main bodyportion ot the cover member 20 may be pushed downwardly, soas to permit `the easy rotation oi the cover meme ber, w'henimoving itto'loelced position.
